Detail from this image: "Diagnostic characters include the pair of medial pronotal spots and the black colouration of the head narrowly encircling around the eyes (in the similar R. binotatus, the black colouration does not encircle the eyes). R. gutticollis is found mainly in streams and is primarily a western species." - Tim Loh, 2009
